我正在尝试获取一个相当大的域列表来查询每个使用compete.com API的排名,如下所示-> https://www.compete.com/developer/documentation

我编写的脚本需要一个我填充的域数据库,并启动一个 cURL 请求来竞争网站的排名。我很快意识到这非常慢,因为每次发送一个请求。我做了一些搜索,发现了这篇文章-> http://www.phpied.com/simultaneuos-http-requests-in-php-with-curl/,它解释了如何在 PHP 中使用 cURL 执行同步 HTTP 请求。

不幸的是,该脚本将采用包含 25,000 个域的数组并尝试一次处理它们。我发现 1,000 个批次的效果很好。

知道如何向competition.com 发送1,000 个查询然后等待完成并发送下一个1,000 直到数组为空吗?到目前为止,这是我正在使用的内容:

<?php

//includes
include('includes/mysql.php');
include('includes/config.php');

//get domains
$result = mysql_query("SELECT * FROM $tableName");
while($row = mysql_fetch_array($result)) {
    $competeRequests[] = "http://apps.compete.com/sites/" . $row['Domain'] . "/trended/rank/?apikey=xxx&start_date=201207&end_date=201208&jsonp=";
}

//first batch
$curlRequest = multiRequest($competeRequests);
$j = 0;
foreach ($curlRequest as $json){
    $j++;
    $json_output = json_decode($json, TRUE);
    $rank = $json_output[data][trends][rank][0][value];

    if($rank) {
        //Create mysql query
        $query = "Update $tableName SET Rank = '$rank' WHERE ID  = '$j'";

        //Execute the query
        mysql_query($query);
        echo $query . "<br/>";
    }
}


function multiRequest($data) {
  // array of curl handles
  $curly = array();
  // data to be returned
  $result = array();

  // multi handle
  $mh = curl_multi_init();

  // loop through $data and create curl handles
  // then add them to the multi-handle
  foreach ($data as $id => $d) {

    $curly[$id] = curl_init();

    $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
    curl_setopt($curly[$id], CURLOPT_URL,            $url);
    curl_setopt($curly[$id], CURLOPT_HEADER,         0);
    curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);

    // post?
    if (is_array($d)) {
      if (!empty($d['post'])) {
        curl_setopt($curly[$id], CURLOPT_POST,       1);
        curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
      }
    }

    curl_multi_add_handle($mh, $curly[$id]);
  }

  // execute the handles
  $running = null;
  do {
    curl_multi_exec($mh, $running);
  } while($running > 0);

  // get content and remove handles
  foreach($curly as $id => $c) {
    $result[$id] = curl_multi_getcontent($c);
    curl_multi_remove_handle($mh, $c);
  }

  // all done
  curl_multi_close($mh);

  return $result;

}
?>

代替

//first batch
$curlRequest = multiRequest($competeRequests);

$j = 0;
foreach ($curlRequest as $json){

你可以做:

$curlRequest = array();

foreach (array_chunk($competeRequests, 1000) as $requests) {
    $results = multiRequest($requests);

    $curlRequest = array_merge($curlRequest, $results);
}

$j = 0;
foreach ($curlRequest as $json){
    $j++;
    // ...

这会将大数组拆分为 1,000 个块,并将这 1,000 个值传递给multiRequest使用 cURL 执行这些请求的函数。

这正是你想要的。只需将空参数传递new Proxy()给绕过代理并发出直接请求。

您可以在其中填充 1000 个请求并调用$proxy->execWait(),它将同时处理所有请求并在一切完成后退出该方法......然后您可以重复。
